DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagram illustrating an internal configuration of a data transmission apparatus according to an embodiment of the present invention. The right side in the figure shows the communication line side, and the left side in the figure shows the data terminal side. Transmission data (SD) input from the DTE port is sent to the DTE control unit via the receiver. Then, SD is modulated by the modulator, and then sent to the line via the loop circuit-analog line interface. On the other hand, the signal received from the line enters the demodulator through the analog line interface-loop circuit and is demodulated. The received data (RD) is sent from the driver via the DTE control unit to the data terminal via the DTE port.
[0013]
The DTE control unit and the modulation / demodulation unit are controlled by the device control unit. In addition, a hardware setting terminal for setting operation conditions of the apparatus is provided, and an apparatus / display unit is further provided.
[0014]
FIG. 2 is a diagram illustrating an example of a front panel switch of the data transmission apparatus. As shown in the figure, the front panel is provided with a power switch and various switches (eight in the illustrated example). Among these, LP1 to LP6 are switches for instructing a loopback test.
[0015]
FIG. 3 is a diagram showing an example of functions set by a setting switch for setting operating conditions. In the setting switch unit (1), AX to MOD0 are set, in the setting switch unit (2), OPT to RL are set, and in the setting switch unit (3), LIN to CD are set. In order to set a desired operating condition, the setting switch shown in FIG. 3 is used.
[0016]
In the present embodiment, a function for confirming whether the wiring of these switches is short-circuited is provided as a test mode.
[0017]
FIG. 4 is a diagram illustrating an example of the setting of the setting switch unit illustrated in FIG. 3. In FIG. 4, the setting switch sections (1) to (3) are set so as to be alternately turned on / off. The device control unit reads the state of the switch shown in FIGS. 3 and 4, but when the switch is normally wired, the device control unit normally reads the bit string in the state shown in FIG. Can do.
[0018]
On the other hand, when the device controller reads a bit string other than the state shown in FIG. 4 in the state set as shown in FIG. 4, it is expected that the switch wiring is short-circuited.
[0019]
As for the panel switch, as shown in FIG. 5, eight switches are alternately turned on / off and read by the apparatus control unit.
[0020]
In the data transmission apparatus according to the present embodiment, a test LED is assigned as a means for notifying the outside of the test result, and the setting switch / front panel switch is alternately turned on / off after the test mode shifts, and can be read as set In this case, the test LED is turned off.
[0021]
If the data read by the device controller does not correspond to the setting state, the test LED remains lit, and in this case, the user can be notified that the wiring is short-circuited.
[0022]
FIG. 6 is a flowchart showing processing in the test mode.
[0023]
When the test mode starts, the test LED lights up. Thereafter, it is determined whether or not a CLR (clear) switch has been pressed. When the CLR switch is pressed, after the initial check is executed, the device shifts to a steady state. On the other hand, when the CLR switch is pressed, it is determined whether or not the CLR switch is pressed again. If the CLR switch is not pressed, the device goes to a steady state.
[0024]
When the CLR switch is pressed, after waiting for 1 second, it is determined whether 5 seconds have elapsed. If the CLR switch is pressed in this state (the CLR switch is continuously pressed for 5 seconds), the test mode is entered. On the other hand, if the CLR switch has not been pressed after 5 seconds have elapsed, the device shifts to a steady state.
[0025]
When the test mode is started, the test LED is turned on after 200 milliseconds have elapsed. Then, it is determined whether or not the state of the setting switch (all of the switches (1) to (3)) is “10101010”, that is, the state in which ON / OFF is alternately set. When the state of the setting switch is as described above, the test LED is turned off. Subsequently, it is determined whether or not the state of the setting switch is “01010101” in accordance with the operation of the setting switch. When the setting switch is in this state, the test LED is turned off. When the setting switch is in any other state, the test LED remains turned on.
[0026]
On the other hand, when the setting switch is not “10101010”, the test LED is turned off after 200 milliseconds have elapsed. Then, the setting state of the front panel switch is confirmed. When the state of the front panel switch is “010101001”, the test LED is turned off, and then it is determined whether or not the front panel switch is set to “10100110” by the operator's setting. When the front panel switch is in this state, the test LED is turned off, but when it is in any other state, the test LED is turned on.
[0027]
In this way, a short check of the connection is performed.
[0028]
FIG. 7 is a drawing showing the procedure of the connection short check.
[0029]
Further, in the test mode, it is possible to easily set the facing test by assigning operation conditions to each switch of the front panel switch as shown in FIG.
[0030]
When the operating conditions are assigned to each switch as shown in FIG. 8, the device control unit monitors the state of the LP switch in the test mode, and when the LP switch is set to ON, the operating condition assigned to the switch is hardened. Hardware (DTE control unit, modulation / demodulation unit shown in FIG. 1).
[0031]
For example, when the LP1 switch is turned on at the own station, the opposite test of the data transmission apparatus can be performed by setting LP2 at the partner station.
[0032]
In the test mode, whether or not the state of the apparatus is normal can be determined by connecting a tester corresponding to the DTE to the data transmission apparatus, sending a test pattern, and determining whether or not a bit error occurs. it can. In addition, the ERRCHK (error check) switch is turned on in both the local station and the partner station, and a test pattern is transmitted from the data transmission apparatus itself to check the bit error status.
[0033]
FIG. 9 is a flowchart for explaining the processing procedure during the facing test described above.
[0034]
Since it is the same as that of FIG. 6 until the test mode is started, the description is omitted. When the test mode starts, it is determined whether any LP switch is on. If no LP switch is on, the process is terminated.
[0035]
On the other hand, if the LP switch is on, it is determined which LP switch is on. Then, as shown in FIG. 8, the corresponding setting is performed according to the LP switch that is turned on. If none of LP1 to LP6 is turned on (or the other switch on the front panel is turned on), the standard setting is set. The standard setting is also set when the LP switch is turned off after the facing test.
[0036]
FIG. 10 is a diagram illustrating an example in which an external I / O device that can be controlled by the device control unit is added to the data transmission device, and the operating conditions assigned to the front panel switch are assigned using an external I / O medium.
[0037]
In this case, for example, a predetermined file such as “testSW.dat” is created on the external I / O medium (shown in FIG. 11), and operating conditions are designated in the file.
[0038]
The file is composed of LP switch number and setting switch unit (1), setting switch unit (2), and setting switch unit (3). The setting switches (1) to (3) correspond to the respective settings shown in FIG. 3 and are entered as bit strings.
[0039]
FIG. 12 is a flowchart for explaining processing relating to operation condition setting using an external I / O medium. When the test mode is entered, the apparatus control unit determines whether there is an external I / O medium. When there is an external I / O medium, the file “testSW.dat” set therein is opened, and when the file is normally read, the LP switch to be set is recognized according to the content. Then, the record corresponding to the LP switch that is turned on is read, and the operation condition is set.
[0040]
On the other hand, if the file cannot be opened normally, the test LED blinks for 5 seconds to inform the user of the fact.
[0041]
FIG. 13 shows a case where an operating condition is assigned to the LP switch in advance, and when the LP switch is set to ON after shifting to the test mode, the operating condition corresponding to the LP switch is not specified in the external I / O medium. FIG. 5 is a flowchart for explaining processing for setting pre-assigned operating conditions.
[0042]
As shown in FIG. 13, the presence / absence of an external I / O medium is determined after shifting to the test mode. If there is an external I / O medium, the same processing as in FIG. 12 is executed. On the other hand, when there is no external I / O medium, the illustrated “CALL LOOP-SW” is executed. This is the process illustrated in FIG. 14 and is similar to the operation in the test mode illustrated in FIG.
[0043]
As described above, according to the present embodiment, it is possible to reduce the number of man-hours for evaluation that is increased by the test mode. In addition, since setting of operating conditions becomes very easy, it is possible to prevent erroneous setting.
